fix(deps): hold typescript below 7 until typescript-eslint supports it

[vpetersson-bot]

Problem

The monthly bun group Dependabot PR in this repo is red, and has been since the group started including typescript 7. The checks job fails at the Lint step with:

ESLint: 10.2.0
TypeError: Cannot read properties of undefined (reading 'Cjs')
    at node_modules/@typescript-eslint/typescript-estree/dist/create-program/shared.js:59
    ...
    at node_modules/@screenly/edge-apps/eslint.config.ts:4:54
error: script "lint" exited with code 1

Cause

@typescript-eslint/typescript-estree builds its default extension set from ts.Extension.Cjs. TypeScript 7 no longer exposes Extension on the public API surface, so ts.Extension is undefined and the module throws at import time — before any file is linted.

This is not a version-skew problem that a newer typescript-eslint fixes. Every published version, up to and including the current 8.70.0, declares:

"peerDependencies": { "typescript": ">=4.8.4 <6.1.0" }

No released typescript-eslint supports TypeScript 7 yet. typescript-eslint reaches this repo transitively through the shared ESLint config in @screenly/edge-apps, so there is nothing to bump here to make TypeScript 7 work.

Fix

Have Dependabot hold typescript below 7 until typescript-eslint supports it. Everything else in the group keeps flowing.

Verification

Reproduced and verified locally on Screenly/clock-app against the open group PR. With typescript at ^7.0.2, bun run lint fails as above. Pinning typescript back to ^6.0.3 while keeping all eight other updates in the group:

bun run lint        ✓
bun run type-check  ✓
bun run test        ✓  7 pass, 0 fail
bun run build       ✓

After merging

Comment @dependabot recreate on the open group PR — it will come back without the typescript bump and should go green.

The same breakage affects every Screenly edge app plus edge-apps-library; an identical change is going up in each.

Duplicate of #12, which already proposes the same fix. Closing this one in favour of the earlier PR.
